Colt1911 [192]

Answer:

The correct answer is e. the passage of electrons from one energy-generating carrier to another

Explanation:

The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.

These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.

Andreas93 [3]

Answer: Conclusion

Explanation:

Scientific method can be defined as a detailed plan for conducting research in a particular scientific domain. This is used to give scientific explanation for natural phenomena. In scientific method a hypothesis is created, observation is made, experimentation is conducted and then finally a conclusion is made to address the hypothesis.

Therefore, after the research is completed the conclusion is made by analyzing all the facts related to the literature and results of the experiments.

Which agent would cause the least damage to a chromosome?
Alex777 [14]
Hey there!

The answer would be ultrasound.


The ultrasound is considered safe because it uses sound waves for the detection of tissue, organ, baby etc. These waves are considered safe and transfer only a small amount of heat to the tissue in which the ultrasound is done. A little amount of heat is not at all harmful to the body in any means. Early defects of baby can be detected through this procedure, the merits of the process is much higher than its demerits.


Hope this helps !
